• 2.05.4(2)(e)(vii) <br />(vii) Soil testing plan for evaluation of the results of topsoil <br />handling and reclamation procedures. <br />Overburden was used to cover the refuse pile to provide adequate <br />cover depth and it was also used as topsoil since no topsoil was <br />salvaged at the mine site. <br />The old spoil pile that was used to cover the development waste <br />disposal area was sampled to determine its geochemistry. The only <br />problem discovered as a result of the tests was one sample had a pH <br />of 4.6. Although the low pH soil is probably not widespread enough <br />to pose a problem for revegetation success, the following <br />procedures were followed to minimize the risk: <br />Soils exhibiting a low pH were be placed in the deeper areas <br />of the fill. <br />After the cover material was in place over the waste disposal <br />area the soils were sampled at the locations shown on Map <br />2.05.4(2)(C)-2 at a depth of 0'to 2'. The following analysis <br />was run on each soil sample in order to develop adequate <br />information to determine required soil amendments: <br />Fertility - Nitrate Nitrogen, Phosphorus, Potassium, Iron, <br />Zinc, Manganese and Copper. <br />Salinity - pH, Electrical Conductivity, Sodium, Calcium, <br />Magnesium and Sodium Adsorption Ratio. <br />Physical - Saturation, Organic Matter and Texture. <br />The results of the soil analysis follow on page 135b. <br />The addition of lime was not necessary since all of the soil <br />samples had a pH value greater than 7.0. Based on the results of <br />the soil analysis the following amendments were added to the soils: <br />Nitrogen 34$ was applied at 42 pounds per acre, Phosphorous 18-16- <br />00 was applied at 87 pounds per acre and Potassium 00-00-60 was <br />applied at 50 pounds per acre. <br />• 135 (Rev. 3-29-96) <br />
